Ultrasound Terminology

The purpose of this information is to help you better understand the differences in terminology that have so many of our patients confused.

Is there a difference between an ultrasound and a sonogram?

Sonogram and ultrasound are two terms that are often used interchangeably. The term Sonogram refers to an ultrasound examination. Ultrasound all by itself refers to the technology used during a sonogram, but there are several other uses for ultrasound technology. When you are pregnant, and you are talking about ultrasounds, more often than not, you are talking about sonograms.

What is the difference between a 2D ultrasound, a 3D ultrasound, and a 4D ultrasound?

Lets start with the differences in the terminology.

• 2D means 2-Dimensional - meaning Length and Width, but not depth.
• 3D means 3-Dimensional - meaning Length, Width, and Depth.
• 4D means 4-dimensional - meaning Length, Width, and Depth over Time.

A 2D ultrasound refers to a regular, black and white sonogram. This examination provides you with an outline of the baby. While this technology has proven very useful, it's shortcoming is that it is often hard for parents, or anyone who does not frequently see ultrasound images to see their baby.

A 3D ultrasound uses the same basic concept of a 2D ultrasound, technology-wise, but rather than take the image from a single angle, the sonographer takes a "volume" image. The volume image that is displayed on the screen is a software rendering of all of the detected soft-tissue - meaning your baby's face, hands, feet, or whatever the sonographer happens to be focusing on. A 3D ultrasound produces a still image.

A 4D ultrasound (also referred to as "Live 3D") extends on the concept of a 3D ultrasound, but rather than taking a single volume image, multiple volume images are taken in rapid succession. The result of these images displayed in succession is a motion video of the baby. You can see movement, such as arm or feet movement, thumb sucking, and even smiling.
